'Well, I'm blowed!' he said again, as we walked up the stair together.
I showed him that the sliver taken from the slipper fitted exactly the interstice I had indicated.
'Now,' said I to him, 'the butler was not going up the stairs, but was coming down. When he fell headlong he must have made a fearful clatter. Shuffling along with his burden, his slipper was impaled by this sliver, and the butler's hands being full, he could not save himself, but went head foremost down the stair. The startling point, however, is the fact that he was not carrying my lord's breakfast to him, or taking it away from him, but that there is someone else in the castle for whom he was caterer. Who is that person?'
'I'm blessed if I know,' said the constable, 'but I think you are wrong there. He may not have been carrying up the breakfast, but he certainly was taking away the tray, as is shown by the empty dishes, which you have just a moment ago pointed out.'
'No, constable; when his lordship heard the crash, and sprang impulsively from his bed, he upset the little table on which had been placed his own tray; it shot over the oaken chest at the head of the bed, and if you look between it and the wall you will find tray, dishes, and the remnants of a breakfast.'
'Well, I'm blessed!' exclaimed the chief constable once again.
'The main point of all this,' I went on calmly, 'is not the disaster to the butler, nor even the shock to his lordship, but the fact that the tray the serving man carried brought food to a prisoner, who probably for six weeks has been without anything to eat.'
'Then,' said the constable, 'he is a dead man.'
'I find it easier,' said I, 'to believe in a living man than in a dead man's ghost. I think I heard his footsteps at midnight, and they seemed to me the footsteps of a person very nearly exhausted. Therefore, constable, I have awaited your arrival with some impatience. The words his late lordship endeavoured to write on the paper were "The Secret". I am sure that the hieroglyphics with which he ended his effort stood for the letter "R", and if he finished his sentence, it would have stood: "The secret room". Now, constable, it is a matter of legend that a secret room exists in this castle. Do you know where it is?'
'No one knows where the secret room is, or the way to enter it, except the Lords of Rantremly.'
